What is claimed is:
1. An apparatus for controlling an engagement rate of a clutch having an inpu£ member and an output member for selectively connecting an engine to a transmission, the apparatus comprising:
a sensor for generating a signal which is representative of the rotational speed of the input member of the clutch;
a sensor for generating a signal which is representative of the rotational speed of the output member of the clutch;
a controller for generating a first control signal when the difference between said clutch input member speed signal and said clutch output member speed signal is less than a predetermined value and for generating a second control signal when the difference between said clutch input member speed signal and said clutch output member speed signal is greater than said predetermined value, said first and second control signals being representative of first and second engagement rates of the clutch, respectively; and
a clutch actuator for controlling the engagement rate of the clutch in response to said first and second control signals.

2. The apparatus defined in Claim 1 wherein said controller is an electronic controller.

3. The apparatus defined in Claim 1 wherein said predetermined value is a constant value.

4. The apparatus defined in Claim 1 wherein said predetermined value is a variable value.

5. The apparatus defined in Claim 4 further including a sensor for generating a signal which is representative of an operating condition of the engine, and wherein said predetermined value is varied in response to said engine operating condition signal.

6. The apparatus defined in Claim 5 wherein said sensor generates a signal which is representative of engine torque.

7. The apparatus defined in Claim 6 wherein said predetermined value is increased in response to a decrease in engine torque.

8. The apparatus defined in Claim 6 wherein said predetermined value is decreased in response to an increase in engine torque.
